New article: Graphs in the database, SQL meets social networks

Lorenzo wrote another impressive sql article :This morning a new article of yours truly has been published on the TechPortal. The title is Graph in the database: SQL meets social networks, and it’s a natural sequel to my talk aboutTrees in the database.
You will learn how to retrieve linked nodes, and how to answer some of the queries typical of social networks like LinkedIn, Facebook, or recommendation systems (“You might also know/like”, “How you are connected to XY”, …).

#Slackware #Linux #Slamd64 and #Firebird

Here is what Milan Babuskov wrote about his experience with Linux Slackware and Firebird related packages on x64 system :

I just installed Slamd64 version 12.2. I know that Slackware -current is 64bit and Slackware 13.0 is out, but out-of-the-box 32bit compatibility of Slamd64 is very tempting, so this is the first 64bit slackware I installed.
Install went fine, and KDE is running in a matter of seconds. Now, time to compile all the needed stuff for development. Basically, all I need is Firebird, FlameRobin and PHP extension for Firebird (i.e. InterBase).

Firebird – 1 terabyte database tests and performance report

We have made 1 terabyte database test with Firebird 2.1. Read more. Questions?

Summary
In this experiment Firebird shows the following results

Undoubted ability to handle big databases. We are pretty sure that it’s possible to create and use 32 Tb database on appropriate hardware, and Firebird will show the same high performance as it shows for smaller databases (i.e., 1Tb and below).

Good scalability and amazingly small footprint. 1Tb database was created at usual desktop computer and, more important, it can be used to perform general queries: if you don’t fetch millions of records, query’s speed is the same as it is for moderate size databases (10-15Gb).
